LASTING-MACHINE'.

SPECIFICATION forming part of Letters Patent No. 232,964, dated October 5, 1880.

Application filed February 2, 1880.

To all whom it may concern:

Be it known that I, GILBERT HAWKES, of Lynn,in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Lasting Boots and Shoes, of which the following is a specification.

The objectof my invention is to provide suitable means for holdin g the uppers of shoes and boots on a last and drawing the lower edges thereof into position for convenient attachment to the soles.

To efiect these results I employ new devices and combinations of devices, which constitute the subject-matter of the appended claims.

In the accompanying drawings, Figure 1 represents a plan view of my improved machine, the griping attachment having been removed. Fig. 2 represents a vertical section through the same. Fig. 3 represents another vertical section at right angles to Fig. 2. Fig. 4 represents a plan view similar to Fig. 1, except that one of the end pieces is withdrawn and some of the lower parts are shown. Fig.5represents a plan view of the auxiliary device'for gripin g. Fig. 6 represents a vertical longitudinal sec tion through the same; and Fig. 7 represents a bottom view of the said auxiliary griping device.

A designates the main frame of the machine, which is provided atits middle with horizontal cross-pieces that support supplementary frame B. These blocks afford a base for a horizontal yoke, O, which has an inner opening somewhat resembling in shape the sole of a shoe, and large enough to allow the passage of the same.

I) design ates a last-holder, which is arranged to be moved vertically in frame B, butprevent'ed from falling out of the same. This vertical motion is derived from an internally screwthreaded j ack or movable block, V, and a screwrod, t, operated by a wheel, S, which engages with said jack.

By means of these devices a boot-upper or shoe-upper may be raised upon the last until its edge which receives the sole is in the space inclosed by yoke G. I next proceed to draw the said edge of the upper into proper position for attachment to the sole. This is effected by means of devices shown in Figs. 5, 6, and 7. A supplementary frame or recessed block,

B, is hinged to the main frame A, so that it can either be turned down upon yoke G and last D or turned upward and backward out of theway. Belowsaidframeasole-shaped downhold,j, is rigidly suspended by means of adjusting-screws 1, which enable the operator to raise and lower this downhold at will.

I arrange a series of gripers, t, each of which consists of a pair of movable jaws suspended respectively from a bar, 75, and from one of a series of hooks, n. Just above the pivot of these jaws an arm formed on one of them is attached to the lower end of a sprin g, 12. There are a series of these springs, all connected at their upper ends to a movable plate, E, which is made vertically adj ustable by means ofa screw-rod, F. These springs operate to close the gripers when the plate E rises and to open them when the said plate falls. The tension ofsaid springs is adjusted by means ofnuts q.

After the upper is in contact with yoke C, or in the space inclosed thereby, as hereinbefore stated, the downhold j is turned down into the space within the curved edge of the upper. The gripers then close upon this edge all around the said blank. It now becomes necessary to fold or bend inward the said edge of the upper, so that it may be in position for the attachment of the sole. To etfect this I em ploya pair of opening and closing heel-lasting jaws and a similar pair of toelastingjaws. Each of the pivoted quadrant-shaped pieces a composing the toe-sections and heel-sections is provided with cogs on its curved outer face, so as to mesh with a cog-wheel or segment, 0, on ashaft, which has a pinion, g, engaged by a sliding rack, G. The two racks G G at one end of the machine are formed on opposite ends of a plate, which is drawn inward by a cord, 4:, which, after passing over suitable pulleys, is attached to jack or block V, The said jaws are closed by means of levers 9 of the first kind, which are operated by hinged. pieces W on opposite sides of said jack. These hinged pieces are operated by the engagementof rollers attached thereto with cams 011 the sides of said jack. The upper ends of said levers force inward the movable blocks which carry the gears c. The effect is to closethejaws aand replace the racks G. The sliding sidelastiug jaws h are forced inward by means of levers r 232mm 3, similar to levers 9, and actuated in like mannor by cams on the side of the jack and intervenin g hinged pieces 10 Springs (one of which is indicated in dotted lines at Z, Fig. 4) serve to move these side-lastin g jaws outward again.

The rising of the jack lifts the last and upper into position for the action of the lastingjaws, and also causes said jaws to close on the projecting edge of said upper and fold it over downhold j. Asole is then fastened to said folded edge of the upper in any convenient manner. The shoe is then released by the downward movement of the jack and its action on the levers and jaws.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the heel-lasting jaws and toe-lasting jaws with jack V, cords 4, levers 9, and intervening gearing for opening and closing said jaws, substantially as set forth.

2. The combination of sliding side-lasting jaws h and opening and closing heel-lasting jaws and toe-lasting jaws a with threaded jack V, screw-rod t, and intervening levers and gears, substantially as set forth.

3. The combination, with lasting-jaws h a, of gripers i,downholdj, and opening and closing devices for said gripers, substantially as set forth.

4. In combination with a vertical moving block, V, having four cam-faces, four hinged pieces, WAW, operated thereby, four levers operated by said hinged pieces, and a sectional frame, a h, operated thereby, as stated.

5. The combination of plate E, spring 12, crossbar 7c, and hinged jaws, forming gripers t, with opening and closing screw F, substantially as set forth.
